TITLE: Agreement 2016-48 with DeLoach Engineering Science, PLLC, for Professional Engineering Services for the Big Slough Flood Reduction Study in the amount of $300,000.00.
Recommended Action
Approve Agreement 2016-48 between the City of North Port and DeLoach Engineering Science, PLLC, for professional engineering services for the Big Slough Flood Reduction Study in the amount of $300,000.00.
Background Information
With the recent completion of the Big Slough Watershed Study and update of the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs), the hydraulic model of the entire Big Slough Watershed is available for additional studies to further define feasible solutions to reduce flooding in portions of the City. The flood reduction study will identify the costs and benefits of alternatives to advance the best solution to a preliminary design, conceptual permitting and identification of land requirements. The study is comprised of two parts.
Part 1 will evaluate methods to reduce localized flooding in two areas. One area is near the Myakkahatchee Creek just north and south of Interstate I-75. The second area is in the Jockey Club west of the Myakkahatchee Creek bounded by Appomattox Drive to the north, and include areas near Pan American Boulevard and Ketona Road. The work will include the necessary field surveying, hydraulic modeling, alternatives analyses, and cost benefit relationships to alleviate flooding in the local neighborhoods during various storm events. The Part 1 budget is $250,000 and up to 50% of this cost will be reimbursed by Southwest Florida Water Management District (SWFWMD) through a cooperatively funded grant.
Part 2 activities will include field investigations, hydraulic modeling, alternatives analyses, and cost benefit assessments needed to advance preliminary concepts to achieve flood mitigation in areas where residential structures are shown as flooding in the recently updated FEMA FIRMs. The work will include identification of candidate site(s), citing of relevant permitting requirements for construction and operation of facilities, and providing cost estimates for detailed design, permitting, land acquisition, and construction. Mixed use of regional storage reservoir facilities will be considered such as, but not limited to, storage for water supply to the City’s water treatment plant, recreational activities, and environmental opportunities such as preserves and water quality improvement. The Part 2 budget is $50,000 and will be funded by the North Port Road and Drainage District.
Proposals were requested from consulting engineering firms for professional services needed for the study. Three (3) proposals were received with DeLoach Engineering Science, PLLC selected as the most qualified firm. Negotiations of the scope and fee were conducted resulting in this Agreement.
